The tank itself is not made of glass. It is acrylic or "plexiglass". I used 1/4" but if i made another i would probly use 3/8 or 1/2" because mine bows out more than i would like... If you look at the pic i did glue a 1" strip along the top ends but not down the lenght. I wish i had and i would have no bowing whatsoever.. Oh well
The contruction of the tank itself is really quick.. The base took me longer to make... I say the whole thing took me a total of ~ 15hrs working time. I got the plexiglass pre-cut to my exact sized by the store and they didnt charge much. The glue is a very this liquid that must be applied with a small needle that you could get from a drugstore.

The middle of my tank has a partion that is removable and i will eventually be cutting it down and but and creating a waterfall from the fish side.. It also hold the take together in the middle.
If you are scared about the joints on the acrylic i wouldnt be.. After glueing and allowing it to set i have tryed many times to break the joint and the plastic before the joint usually breaks first so the joint is actually harder than the plastic itself.
After buling it i read and realized that i might have made mistake in using acrylic after reading on here that there claws may scratch the tank but meh. I like it.
